Jkmd multi rope friction hoist

 Jkmd multi rope friction hoist

   Jkmd multi rope friction hoist It is a large-scale mechanical equipment for transportation by changing potential energy, such as mine hoist, dam hoist, etc. Broadly speaking, elevator, crown block, winch, stable car, crane, hoist, etc. can be called hoist. Hoist generally refers to large mechanical equipment with large power and strong lifting capacity. The transportation process is completed by driving the flexible steel wire rope and the transported goods up and down by power machinery. The steel wire rope is an indispensable part of lifting machinery, and the main varieties include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope, smooth steel wire rope, etc.

   Product features, main uses and scope of application:

This product is mainly used in coal mine, metal mine and non-metallic mine for lifting minerals, lowering materials, lifting personnel and equipment. As the electrical equipment of this product is non explosion-proof, it can not be used in places with gas, coal dust and other flammable and explosive media.

The products comply with the enterprise standard of Q / hbwf006-2014 multi rope friction hoist, aq1036-2007 safety inspection specification for multi rope friction hoist for coal mine and GB / t10599-2010 multi rope friction hoist.

   working principle:

When the main motor is started, the motor rotor transmits the power to the high-speed shaft of the reducer through the elastic coupling. After being driven and decelerated by the reducer, the passive shaft of the reducer is transmitted to the main shaft device through the gear coupling. The multi rope friction hoist adopts the principle of flexible body friction transmission. The steel wire rope is laid on the friction wheel, and the steel wire rope and friction pad are used To lift or lower heavy objects or personnel.

   Safety regulations:

The hoist is maintained and managed by the designated personnel, and the key of the power switch box is managed by the designated personnel.

The hoist shall be equipped with winch limiter and travel limiter. The limiter shall enable the pulley to stop automatically when it is lifted to 300 mm away from the drum or pulley. The operation is sensitive and reliable, and trial hoisting is carried out.

The hoist shall be marked with heavy load, and the weight shall not be overloaded (1t) during lifting and landing.

After power transmission, check the safety devices such as winch limiter, travel limit device and interlock switch

Before lifting and landing, the car can be started only after the bell is sounded for warning.

The hoist is not allowed to carry people up and down.

After the work is finished, the hoisting plate of the hoist should fall to the ground, then cut off the power supply and close the upper and lower guardrail doors.

Keep the environment around the elevator clean.

   matters needing attention:

Start up with no load. Therefore, all materials in the hopper should be drained before each shutdown, and then the machine is stopped.

It can't be reversed. Reverse that may occur chain derailment phenomenon, troubleshooting derailment is very troublesome.

Feed evenly. Sudden increase of feed rate is prohibited. The feeding rate shall not exceed the conveying capacity of the hoist. Otherwise, it is easy to cause the material accumulation at the bottom, and the vehicle will be blocked seriously.

Replenish lubricating oil timely and appropriately.

When the chain and hopper are seriously worn or damaged, they should be replaced in time.
